  8. 8. © Copyright IBM 2014 What is 'Andy' the developer like? Driven to produce applications that can be field tested in the minimum time possible Discovers technology that are prevalent in his communities Uses the best tool for the job Intolerant of process / company mandates / imposed technology that do not obviously and immediately benefit his application 8
  9. 9. © Copyright IBM 2014 Some more background WebSphere MQ is a fully featured messaging product that caters for even the most advanced messaging topologies It has support for a wide array of languages, platforms, architectures, qualities of service, topology types, high availability configurations, workload balancing etc... However, while administrators tend to be well skilled in MQ technologies, application developers tend not to be. Architects are being asked to do more with less These are just some of the graphics from the Intro to MQ presentation Application developers have less time to learn the MQ product thoroughly
  10. 10. © Copyright IBM 2014 What is MQ Light (beta)? 1. A new messaging API 1. A messaging runtime for on-premise development and deployment 1. A PaaS messaging runtime for admin-free cloud deployment (Elastic MQ service) More on all of these throughout the slides...

  13. 13. © Copyright IBM 2014 Application Messaging Features Our new messaging offering will focus on the developer... •A simple API •Developer-oriented download & install process •Web based tooling •Open-source technologies •Easy to deploy apps to a PaaS environment e.g. client.connect() client.send() client.subscribe() client.unsubscribe()
  14. 14. © Copyright IBM 2014 Developer oriented download & install We're addressing the inhibitors to developer approval  Removing the sign-in step from the download process  Removing the need to run an installer, allowing the product to be unzipped to any location  Ensuring we don't require intrusive OS changes, e.g. altering the registry, setting up users  Developer-centric platform support (see next slide)  Providing a more developer-centric look & feel to the download site and support pages
  15. 15. © Copyright IBM 2014 Appropriate Platform Support Developer-centric rather than enterprise-centric platforms – The beta currently has support for: • Microsoft® Windows® 7 • RedHat Enterprise Linux 6 64-bit – We recognise the importance of platforms and we'll be looking at support for them during the beta, such as: • Ubuntu • Mac OS X • Suse Linux z/OS, IBM i, Solaris®, AIX or HP-UX® are not our target platforms
  16. 16. © 2014 IBM Corporation Agenda - Introduction & Background - Use-case and features - A new messaging API - Deploying apps & IBM BlueMix - Demo
  17. 17. © Copyright IBM 2014 Simple API Better suited to rapid application development Basic administration built into the API • Creating endpoints, configuring connectivity to existing systems etc. Based on AMQP 1.0 • Open protocol to encourage community development • Intention is to open-source the clients (statement of direction) • Language-specific libraries will be provided so the developer doesn't code directly to the AMQP spec • Node.js currently available in the MQ Light alpha available online Designed to fit in with what developers are used to • How quickly and easily can client libraries be added to your runtime of choice? • Libraries available via appropriate repositories e.g. npm install mqlight
  18. 18. © Copyright IBM 2014 Current ideas for API features ● Message content ● Text and Binary message types ● Message properties ● Message delivery ● TTL on messages ● TTL on destinations ● Delivery delay ● Read-ahead buffer ● Require-subscriber (fail publish if no subscribers) ● Quality of service ● At most once message delivery ● At least once message delivery ● Acknowledgement of messages in client or application (Bold = available in beta today, otherwise ideas for future beta updates)
  19. 19. © Copyright IBM 2014 Node.js API design ● Uses callbacks on most API functions, e.g. client.connect(function(err) { If (err) { console.log(“Connection failed!”); } }); ● State-change callbacks client.on('connected', function() { console.log("Connection made”); console.log("About to published our first message...”); … }); ● No plans to use Promises in the API ● Better suited to callbacks which are only called once
  20. 20. © Copyright IBM 2014 Node.js API design ● Whatever object is passed into the send is received by the subscriber client.send(topic, “Hello World”); // Receiver gets a string client.send(topic, new Buffer([12,32]); // Receiver gets a buffer client.send(topic, {color:'red',size:'10'}); // Receiver gets JSON ● Many function parameters optional // Simple publish client.send(“sports/football”, “Arsenal 1, ManU 0”); // Publish with some options client.send(“sports/football”, “Arsenal 1, ManU 0”, {deliveryDelay:1000, ttl:100}); // Publish with options and a callback client.send(“sports/football”, “Arsenal 1, ManU 0”, {deliveryDelay:1000, ttl:100}, function(err) { // Handle failed send });
  21. 21. © Copyright IBM 2014 MQ Light Messaging Model – Send Messages Applications send messages to a topic. A topic is an address in the topic space either flat or arranged hierarchically. 1. Send (‘/test/a’, “Hello”); 2. Send (‘/test/a’, “World!”); Topic Address Space Sender application
  22. 22. © Copyright IBM 2014 MQ Light Messaging Model – Simple Receive • Applications receive messages by creating a destination with a pattern which matches the topics they are interested in. • Pattern matching scheme based on WMQ. 1. Send (‘/test/a’, “Hello”); 2. Send (‘/test/a’, “World!”); 1. Hello 2. World! Topic Address Space Sender application DESTINATION Pattern=/test/a
  23. 23. © Copyright IBM 2014 MQ Light Messaging Model – Pub/Sub • Multiple destinations can be created which match the same topic • Pub/Sub style. DESTINATION 1. Send (‘/test/a’, “Hello”); 2. Send (‘/test/a’, “World!”); 1. Hello 2. World! 1. Hello 2. World! Topic Address Space Sender application DESTINATION Pattern=/test/a Pattern=/test/# Client 1 Client 2
  24. 24. © Copyright IBM 2014 MQ Light Messaging Model – Persistent destinations • Destinations persist for a defined “time to live” after receiver detaches. 1. Send (‘/test/a’, “Hello”); 2. Send (‘/test/a’, “World!”); Topic Address Space Sender application Hello World! DESTINATION Pattern=/test/a Disconnected client
  25. 25. © Copyright IBM 2014 MQ Light Messaging Model – Sharing • Clients attaching to the same topic pattern and share name attach to the same shared destination. DESTINATION1. Send (‘/test/a’, “Hello”); 2. Send (‘/test/a’, “World!”); 1. Hello 2. World! 1. Hello 2. World! SHARING Topic Address Space Sender application DESTINATION Pattern=/test/# Pattern=/test/# Share=myshare Client 1 Client 2 Client 3
  26. 26. © Copyright IBM 2014 MQ Light Messaging Model – Client takeover 1. Send (‘/test/a’, “Hello”); Hello Topic Address Space Sender application DESTINATION Pattern=/test/# Client 1 World! Client 1 2. Send (‘/test/a’, “World!”); • Applications connect to MQ Light service specify (optional) client ID. • Re-using the same client ID pre-empts the original connection. • Ideal for worker takeover in the cloud.

  30. 30. © Copyright IBM 2014 IBM MQ Light – for on-premise deployment Some developers will like the new APIs but won't want to deploy to a PaaS – Small line-of-business projects, e.g. queueing up builds – No mission critical features • No HA • No horizontal scaling MQ Light will probably be available to license as the production runtime for messaging applications – Specific licensing plan not yet finalised – Looking at licensing models that work for development teams Fully compatible with the IBM Elastic MQ service in BlueMix – Easy to migrate applications to a PaaS at a later point

  32. 32. © Copyright IBM 2014 IBM Elastic MQ service - Messaging in a PaaS MQ currently offers cloud deployment options in a couple of flavours – IBM Messaging Extension for Web Application Pattern (IBM PureApp, IBM WD) – WebSphere MQ Hypervisor Edition for AIX/RHEL We also have a beta version of Elastic MQ running in the IBM BlueMix PaaS – Admin-free experience – MQ environment automatically provisioned for each user when they request an instance of it – Applications are linked or 'bound' to the provisioned environment automatically when they are deployed to BlueMix – The MQ Light team are working with BlueMix to offer a seamless development-to- production experience. – Not a full MQ experience in the cloud
  33. 33. © Copyright IBM 2014 How does MQ Light fit in PaaS development? The intention is for MQ Light to provide a (probably free) development environment for applications that will deploy against IBM Elastic MQ in BlueMix Gives the developer 2 choices for development: 1. Develop directly in BlueMix. As you make changes to your code you push the new version straight to BlueMix and check your changes are OK 2. Develop on your laptop using MQ Light. Once you're 90% complete, start pushing your app to BlueMix to try it out in the cloud and iron out any remaining bugs. MQ Light offers an offline development environment – Provides a development version of the messaging service that will be offered in the cloud – Makes offline application development possible when connectivity to the cloud is not available – Comparatively small download & install footprint to get you started quickly & easily
